To all whom it may concern:

- Be it known that LLours WITRY, a citizen of the- United States of 'America, and a' resident of Waterloo,

Blackhawk county, Iowa, have invented certain new and useful Improvements in Speed-Regulating Devices for Explosive Engines, of which the following is v a specification.

My invention relates to speed regulating devices for explosive engines, and the object of my improvements which'are illustrated is to provide means whereby an engine governor'niay be influenced at will to retardor enhance the speedflof the engine. This object I have effected by the means which are hereinafter. described and claimed, and in the accdlnpanying drawings,

in which--" Y Figure 1 is a plan view of an engine. governor supplied with myim'provedspeed reguIatorQand' Fig. 2 is a side elevation of the same; 3

Similar letters refer to similar parts several views. t p

Fastened .to the en bracket 0,-which has a bearing r projecting inwardly to receive the shaft of the governor yoke t.-" Said shaft also has-a bearing perforation to receive a slidable rod q. .The governor balls 8, s have their inwardly bentstems a, u pivoted to the yoke t on pivot bolts 1), a, the

. inner ends of said stemsriearly touching, and in con tact with the. inner end of-the rod q. The balls 8, s have hooks x,'a: and x, x, on opposite sides thereof, to

which are connected contractile springs to and w respectively. The outer end of the shaft of the yoke-t bears a pinion 1), whereby rotation is imparted to said gbvernorballs s, s by any suitable source of power applied throughany convenient system of intermediate gearing. .The outer end of the rod q projects a sufiicient distance beyond the outer face of the pinion. p, and is contacted by the free end of a ilats'pringn, the latter having its other end fastened to the outer-side of a rock-body m by screws 11/. The rock-body m is sup; ported by a-pe rfora ted lugo, a stud y projecting from the rock-body m into said perforation in said lug. Said lugprojects outwardly from the bracket 0; Anextension member 1 projects from the side of the rock-' body m, and bears aprojecting spring 7:. .A plate b having a perforated lug dis affixed to the engine bed a' by means of bolts c. A handle lever. c has its lower end pivoted on ashort shaft f, the latter being mountedin the perforation in the lug d. The rock body at has an inwardly extending pin. 1: between whose end throughout the ine frame'a by bolts o is a and the handle 0 a contractile spring g is connected.

In case this feed regulator is used on a gasolene engine,'- the rod 1' whichactuates the igniter and exhaust valve has a block) attached to it by means of bolts z, a plate z shorter than the said blocl; being fastened thereto by:

the said bolts. The exposed outer surface: of the block j adjacent to the end of the plate 2 is positioned so that the same may be instantly effected by simply throwing the handlever e'forward a sui ficient distance, said lever thus, through its elastic connection 9 and the pin h, rocking the rock body wt so that the free end'of the spring/n. pushes npon the rod q and produces a resistance tothe centrifugal force of the balls and thus causes a higher speed of the engine. The rocking of the rock .body m causes the displacement outward of the spiing bellowing the block j and rod i to freely move, .If it is; j desired to' slow upjgie engine the handle e isithrust rearward a suflicient'distancecausing .a reversal'of the above process. The spring 70 then, through the action of the governor, more easily interferes-with the sliding action of the block j and the-rod i. By thrdwing-the lever e'hackward is stopped.

new, and desire to secure by Letters Patent, is V In a speed regulating device for explosive-engines, the

combination with the engine frame, of centrifugal 'governor-balis mounted on levels pivotally connected to a to its limit of movement ,the engine Having'described my invention, what I claimas i rotatable sleeve, such levers havinginwardly directed members, a'slidable pin in said sleeve and projecting from each end thereofundhavlng one end, in contact with the inner sides of such inwardly directed members, a valve-rod and having a contact block atiixed thereto, a rock-body 'pivotnl'ly mounted on said frame having an arm adapted to rock into the path of said'contact-block to contact the'i'e vithand intercept its motion, such rock-body having another arm adapted to contact with the outer end of said sliduhle pin, and such took-body having a projection inwardly directed, a'hand-lever pivoted to said frame, and.

a resilient connection between said hand-lever and the projectloninwnrdly projected from said rockbo'dy.
